Anastomosis groups of <i>Rhizoctonia solani</i> associated with soybean root and hypocotyl rot in Ontario and resistance of accession PI 442031 to different anastomosis groups
Bibliographic record
Abstract
Rhizoctonia solani is a complex species and causes soybean root and hypocotyl rot worldwide. Identifying anastomosis groups (AGs) prevalent in a region and growing cultivars with resistance specific to those AGs is a potential means to minimize economic losses from this disease. The main objectives of this study were (i) to identify the predominant AGs of R. solani associated with soybean root and hypocotyl rot in Ontario using both anastomosis grouping and polymerase chain reaction with AG-specific primers; and (ii) to determine the resistance of the soybean accession PI 442031 to different AGs. In 2 years, 278 R. solani isolates were recovered from diseased soybean plants across Ontario and classified into AG-2-2 IIIB (86.0%), AG-4 (1.4%), and AG-5 (12.6%). In general, isolates of AG-2- 2 IIIB were more aggressive than isolates of AG-4 and AG-5. PI 442031 was moderately resistant to all isolates of AG-4 and AG-5, but was highly susceptible to most AG-2-2 IIIB isolates

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
